math.random

[donacool]

can someone tell me how do i use a math.random but that it only be 1 to 2

like fisrt 1 then 2 then 1 then 2 then 1 then 2

 

[Derek Boom Boom]

local num = math.random(1, 2)

If it's not that what you want, try:

local num = 1

function xxx()
num = num == 1 and 2 or 1
end

You better use local num = -1 in second example, so counting will start from 1.

no like this

function onStepIn(item, position, lastPosition, fromPosition, toPosition, actor)
local alphaTeam = {x = 1000, y = 1000, z = 7}
local bravoTeam = {x = 1000, y = 1000, z = 7}
local number = math.random(1, 2)
local tileid = 474
local tileuid = 1897554

if isPlayer(cid) and item.itemid == tileid and item.uid == tileuid then
	if number == 1 then
		doTeleportThing(cid, alphaTeam)
		doSendTextMessage(cid, CONST_ME_DESCR, "You are a alpha teamer!")
	end return true
	elseif number == 2 then
		doTeleportThing(cid, bravoTeam)
		doSendTextMessage(cid, CONST_ME_DESCR, "You are a bravo teamer!")
	end return true
end
return true
end

its okey?
im not sure if i need to put so mant returns true
please post something that can help me

local dest = {
	[1] = {x = 1000, y = 1000, z = 7},
	[2] = {x = 1000, y = 1000, z = 7}
}

local names = {"Alpha", "Bravo"}

local tileid = 474
local tileuid = 1897554

function onStepIn(item, position, lastPosition, fromPosition, toPosition, actor)
	if isPlayer(cid) and item.itemid == tileid and item.uid == tileuid then
		local number = math.random(1, 2)
		doTeleportThing(cid, dest[number])
		doSendTextMessage(cid, CONST_ME_DESCR, "You are a ".. names[number] .." teamer!")
	end
end

you can also use

• math.random() with no arguments generates a real number between 0 and 1.
• math.random(upper) generates integer numbers between 1 and upper.
• math.random(lower, upper) generates integer numbers between lower and upper.

math.random(2)

 

[Derek Boom Boom]

don't include the two integers

math.random(2)

By the way: no difference

yes, we know, it's just knowledge
